Liner Replacement and Accessory Refurbishment
Does your pool have a worn, discolored, or torn liner? At ARG Piscinas, we specialize in replacing reinforced liners. We remove your old liner and replace it with a state-of-the-art reinforced liner with 3D textures, anti-slip properties, and modern colors. Give your garden a whole new look quickly and cleanly.When is it time to change it?
A liner has an expiry date, and the signs of this are visible before a leak occurs.
Worn or faded
PVC loses its colour and texture after years of exposure to chlorine and sunlight; this is a sign that the material is reaching the end of its life.
Torn or creased
A liner without internal reinforcement is vulnerable to impact and pressure, and once it breaks, it cannot be repaired: it must be replaced.
Leaking fittings
The frames around the skimmers, jets and spotlights are the points where water loss reoccurs, and they are inspected on site.
the process of changing the liner
What happens in your swimming pool every day?
Day 1 — Emptying and removal
Empty the bath and remove the existing lining: liner, loose paint or unsalvageable tiling. Carry out a structural inspection to identify cracks and areas requiring repair.
Day 2 — Repair and preparation
Cracks are repaired using a specialised mortar, the surface is levelled where necessary, and perimeter anchoring profiles – made of stainless steel or PVC – are fitted.
Day 3 — Geotextiles and pattern-making
The geotextile is laid out over the entire reservoir and the layout is planned: the cutting and arrangement of the panels on the surface, in accordance with the preliminary plans.
Day 4 — Hot welding
All joints between panels are welded using a hot-air welder. This is the most technical stage: each weld is checked with a test probe to verify penetration.
Day 5 — Sealing, fittings and filling
The perimeter joints are sealed using the manufacturer’s sealant, the frames for the skimmers, jets and spotlights are fitted, and the pool is filled.
Liner or reinforced liner: how do they differ?
Both are water-retaining, but they are not the same product. The difference starts with the thickness and ends with how many years pass before the next construction project.
| Liner | reinforced liner | |
|---|---|---|
| Thickness | 0.4 – 0.6 mm | 1.5 mm minimum |
| Internal reinforcement | No structural reinforcement | Polyester mesh |
| How to fit it | It stretches across the glass | It is hot-welded, panel by panel |
| Service life | 8–12 years | It can last for more than 20 years |
| 8 × 4 swimming pool | €3,000 – €4,500 | €4,000 – €6,500 |

Between three and five working days for a standard residential swimming pool. The timeframes by size are as follows: the installation time guide.
